I'm 29 & had blood test for vitamin d. result vitamin d3 level - 30, advised to take 50,000 iu for 8 weeks. any alternatives?

What is the concern?: That vitamin D level is essentially normal, though other authorities may argue for higher cutoffs. if you are concerned about taking 50,000 IU vitamin D for 8weeks, then I would question your prescribing doctor about the desired vitamin D level that he/she is trying to achieve and why.

Likely: NATURAL vitamin D3 5,000 IU a day to reach and maintain a level of 50-66 ng/mL. HRS, MD, FACC www.thepmc.org
